Strata Senior NUSD

Senior NUSD (srNUSD) is an over-collateralized, yield-bearing synthetic dollar backed by NUSD, representing the senior risk tranche in Strata’s structure. It offers superior risk-adjusted yield by providing protection against underlying strategy risks and guaranteed minimum yield tied to the benchmark rate (Ethena sUSDe APY), while retaining uncapped upside participation in sNUSD APY.

srNUSD always earns a share of the yield generated by the protocol on the pooled NUSD collateral by staking NUSD. Its yield has a floor equivalent to the benchmark rate ensuring uncapped upside exposure to sNUSD APY with minimum guaranteed yield and first-loss protection provided by the junior tranche. In extreme scenarios, srNUSD APY will be equivalent to the sNUSD APY.
